Brief description of the drawings

Accompanying drawing 1 is structural representation of the present invention.

Accompanying drawing 2 is circuit theory diagrams of the present invention.

Embodiment

As shown in accompanying drawing 1,2, the present invention includes housing 1 and be arranged at a pair of Siemens 2M line interface 2-1,2-2 and a pair of BNC2M line interface 3-1, the 3-2 on housing 1, on described housing 1, be provided with core break-make pilot lamp 4, screen layer break-make pilot lamp 5 and short circuit pilot lamp 6, in described housing 1, be provided with 2M cable testing circuit, described 2M cable testing circuit is made up of core detecting unit, screen layer detecting unit and cable short-circuit detecting unit.

Described core detecting unit is made up of battery E1, current-limiting resistance R2, light emitting diode D2, described current-limiting resistance R2 is connected on the core end of battery E1 positive pole and Siemens 2M line interface and BNC2M line interface, the core termination battery E1 negative pole of described Siemens 2M line interface and BNC2M line interface after connecting with light emitting diode D2;

Described screen layer detecting unit is made up of battery E2, current-limiting resistance R3, light emitting diode D3, described current-limiting resistance R3 is connected on the screen layer end of battery E2 positive pole and Siemens 2M line interface and BNC2M line interface, the screen layer termination battery E2 negative pole of described Siemens 2M line interface and BNC2M line interface after connecting with light emitting diode D3;

Described cable short-circuit detecting unit is made up of battery E1, battery E2, light emitting diode D1, current-limiting resistance R1, the positive pole of described battery E1 is connected on the screen layer end of Siemens 2M line interface and BNC2M line interface after the negative pole of current-limiting resistance R1, light emitting diode D1, battery E2, and the negative pole of described battery E1 is connected on the core end of Siemens 2M line interface and BNC2M line interface.

The course of work of the present invention is as follows:

When measurement, handle is connected to respectively " A, the B " and " A`, B` " in figure by survey line two ends.

(1) detect whether conducting of core, if tested wire core conducting, core break-make pilot lamp 4 is luminous;

(2) detect whether conducting of screen layer, if by the conducting of survey line screen layer,, screen layer break-make pilot lamp 5 is luminous;

(3) when having detected under the prerequisite of core and the conducting of screen layer single channel, detect between screen layer and core whether short circuit, if now short circuit pilot lamp 6 is luminous, illustrate that core and screen layer are short circuits, be malfunction.

So, only have when core break-make pilot lamp 4, cover a layer break-make pilot lamp 5 and manage luminously, and short circuit pilot lamp 6 manages when not luminous, circuit is only normal condition.
